Fluoride specifically adsorbed to hydroxyapatite reduces the rate of dissolution of hydroxyapatite. Since specific adsorption is a property which anions of all weak acids have in common, it is expected that the anions of lactic and acetic acid will be specifically adsorbed to hydroxyapatite too and
OBJECTIVE
The literature reports the merits of antibacterial, antibiotic and steroid agents in treating otological infections but no controlled clinical trial has directly compared 2% glacial acetic acid (EarCalm; Stafford-Miller Ltd, Brentford, UK) against 2% glacial acetic acid, 0.1% dexamethasone
Acetic acid acts as one component of the mobile phase to influence separation of puerarin from daidzin when using β-cyclodextrin-substituted media. In this work considering an explicit acetic acid solution, host-guest complexes of β-cyclodextrin (β-CD) with puerarin and daidzin were investigated by
We report the absolute absorption cross sections of the fourth vibrational O-H (5ν(OH)) overtone in acetic acid using cavity ring-down spectroscopy. For compounds that undergo photodissociation via overtone excitation, such intensity information is required to calculate atmospheric photolysis rates.
The synthesis and preliminary pharmacological profile of a new series of muscarinic antagonists, derived from previously studied 2,2-diphenyl-2-ethylthio-acetic acid esters, are reported. The parent molecules were decorated with linkers of different length, carrying an amino group to catch a
A chemical system for lesion production was used. The influence on lesion characteristics of the concentration of undissociated acetic acid in a calcium and phosphate-containing buffer solution was investigated. Artificial lesions obtained after demineralization in buffers with a pH of 4.0, 4.5, 5.0
This study assessed the effectiveness of models for developing subsurface caries lesions in vitro and verified mineral changes by transverse microradiography (TMR). Enamel blocks from permanent (n=5) and deciduous teeth (n=5) were submitted to lesion induction by immersion in demineralizing
This in vitro study evaluated the effect of fluoride varnishes on caries development in primary tooth enamel using polarized light microscopic techniques. A total of forty extracted or exfoliated primary teeth with intact, caries-free smooth surfaces underwent a fluoride-free prophylaxis and soft
Protein-imprinted cavities bearing exchangeable domains to be used for postimprinting fluorophore introduction to transform binding events into fluorescence changes were constructed in molecularly imprinted polymer (MIPs) matrixes prepared on glass substrates. Copolymerization was performed with
Auxin is a crucial phytohormone for precise control of growth and development of plants. Due to its low concentration in plant tissues which are rich in interfering substances, the accurate determination of auxins remains a challenge. In this paper, a new strategy for isolation and enrichment of
We prepared lysozyme-imprinted polymers bearing modifiable sites within the imprinted cavity to introduce various functional groups via post-imprinting modifications. For this purpose, ({[2-(2-methacrylamido)-ethyldithio]-ethylcarbamoyl}-methoxy)acetic acid (MDTA), which has a carboxy group to
During seed germination, sugars and auxin are produced from stored precursors or conjugates respectively, and transported to the seedling axis. To elucidate the mode of travel of indole-3-acetic acid (IAA) into the phloem, a solution of [(3)H]IAA, together with [(14)C]sucrose, was injected into the
